Determination of quark-antiquark component of the photon wave function for u, d, s quarks

摘要

Based on the data for the transitions pi(0), eta eta' -> gamma gamma*(Q(2)) and reactions of the e(+)e(-) annihilations e(+)e(-) -> p(0), omega, phi and e(+)e(-) -> hadrons at 1 < Ee+e- < 3.7 GeV, we determine the light-quark components of the photon wave function gamma*(Q(2)) -> q (q) over bar (q = u, d, s) for the region 0 greater than or similar to Q(2) greater than or similar to 1 (GeV/c)(2).
